High-End Computing Program

Delivering high-end computing systems and services to NASA's aeronautics, exploration, science, and space technology missions.


If you are a NASA-sponsored scientist or engineer, computing time is available to you at the High-End Computing (HEC) Program's NASA Advanced Supercomputing (NAS) Facility and NASA Center for Climate Simulation (NCCS).

01.19.21 - 2020 HEC Needs Assessment Report Now Available
The NASA High-End Comuting (HEC) Needs Assessment report documents the HEC users’ needs raised during a virtual workshop that took place June 1–19, 2020 in terms of computing capacity, technology, services, human resources, and programmatic. The HEC Program will use the information to develop future investment and program implementation strategies.

09.29.21 - NASA Field Campaigns Resume with GMAO and NCCS Support
After delays due to COVID-19, NASA and partner organizations enthusiastically mounted several field campaigns in spring-summer 2021. Key to campaign success are 12-kilometer-resolution atmospheric forecasts provided by NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office (GMAO) and NASA Center for Climate Simulation (NCCS).

09.27.21 - Yale Astronomer Leads Team in the Study of an Ultra-Hot Jupiter
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of researchers has discovered an alien world nearly two times larger than Jupiter. TESS observations are processed by the Science Processing Operations Center (SPOC), which generates calibrated pixels and light curves on the Pleiades supercomputer at the NASA Advanced Supercomputing (NAS) facility..

09.23.21 - GMAO Science Snapshot: Sub-city Scale Hourly Air Quality Forecasting by Combining Models with Observations
To better understand air quality risks and mitigate impacts, Global Modeling and Assimilation Office (GMAO) scientists propose a method incorporating outputs of NASA’s GEOS Composition Forecasting (GEOS-CF) model system with satellite information from ESA’s TROPOspheric Monitoring Instrument (TROPOMI) and ground measurement data from the EPA network in the continental United States. GEOS-CF runs at the NCCS.

09.13.21 - The Rock That Ended the Dinosaurs Was Much More Than a Dino Killer
In this New York Times interview, NAS user Bill Bottke from the Southwest Research Institute described NASA’s Pleiades supercomputer as a “game changer” for his research team, which ran simulations of 130,000 model asteroids evolving over hundreds of millions of years—including the one that may have killed off the dinosaurs
